[0024] The blocking plate 2 can be used to seal both ends of the square steel pipe 1, so that the square steel pipe 1 and the blocking plate 2 form a sealed box. The square steel pipe 1 can be used to support and reinforce the bottom of the internal threaded sleeve 3. Through the threaded connection between the internal threaded sleeve 3 and the external threaded screw 4, the extension length of the external threaded screw 4 can be adjusted, thereby changing the working height of the Y-type bracket 6. The forward and reverse adjusting sleeve wrench 8 and nut 5 can be used to assist the rotation of the external threaded screw 4 inside the internal threaded sleeve 3. Through the rotational connection between the external threaded screw 4 and the Y-type bracket 6, the Y-type bracket 6 can be kept from rotating when the external threaded screw 4 rotates, thereby improving the stability of the Y-type bracket 6 during height adjustment.

[0025] Example 2: Figures 1-5 As shown, a double bearing 12 is attached to the bottom of the square steel pipe 1. A bearing shaft 13 is inserted inside the double bearing 12. One end of the bearing shaft 13 is equipped with two end plates 10, and the other end is equipped with a partition plate 16.

The connection between plug 2 and threaded rod 22 can be assisted by hexagonal nut 20. The rotation of threaded rod 22 can be driven by adjusting socket wrench 21. The two end plates 10 can support the installation of internal threaded sleeve 23. Through the threaded connection between internal threaded sleeve 23 and threaded rod 22, plug 2 can be driven to move above double bearing 12 when threaded rod 22 rotates, thereby adjusting the position of Y-shaped bracket 6 and pipe body 25 and assisting in the alignment of pipe body 25. The connection between multiple devices can be assisted by connecting angle steel 28. The installation and fixation of threaded rod 27 can be assisted by connecting nut 26, thus facilitating the installation and use of the entire device.

[0027] The usage and working principle of this device are as follows: First, a box is formed by square steel pipe 1 and blocking plate 2. A hole is made at the center of the upper part of the box. An internal threaded sleeve 3 is inserted through the hole, and its lower end is welded to the bottom of the box. Its upper part is welded to the hole in the upper part of the box. An external threaded screw 4 is screwed into the internal threaded sleeve 3. Two nuts 5 are welded on the external threaded screw 4 in sequence. A forward and reverse adjusting sleeve wrench 8 is installed on the outside of the lower nut. A Y-shaped bracket 6 is installed on the outside of the upper nut 5. Two single bearings 7 are installed on the upper part of the Y-shaped bracket 6. The bottom plate 9, the two end upright plates 10, the top plate 11 and the side upright plates 15 are welded into a cuboid. The partition plate 16 divides the internal space of the cuboid. A long groove is left at the top of the top plate 11. Four short channel steels 14 are welded to one side of the upper part of the top plate 11 and holes are drilled in the upper part. Holes are made at the bottom of the two end upright plates 10 and bearing shafts 13 are inserted. Double bearings 12 are installed side by side on the bearing shafts 13. A positioning tail rod 24 is welded to one end of the box. One end of the tail rod 24 passes through the two end plates 10, and the other end is equipped with a rotatable threaded rod 22. A hexagonal nut 20 is connected to the side of the square steel pipe 1 of the box and can rotate. A positive and negative adjusting socket wrench 21 passes through the threaded sleeve 23 inside the threaded sleeve. The positive and negative adjusting socket wrench 21 is installed at the tail end of the threaded rod 22. After the short channel steel 14 and the L-shaped connecting plate 18 are fixed with the base plate 9, they are placed on the channel steel bracket 17. The pipe body 25 is placed on the Y-shaped bracket 6 to form device one. Two devices one are processed and connected by connecting angle steel 28 to form an integral device. A hole is drilled in the center of the device to install threaded rod 27, which is fixed with connecting nut 26. The upper part of threaded rod 27 is fixed with the top plate 11. It is not necessary to weld the short channel steel 14 and the L-shaped connecting plate 18 to form device two. It is set in the device that needs to be welded together, using threaded rod 27 or bracket, and installed under the roof.

[0028] The external threaded screw 4 and the Y-type bracket 6 are connected by a loose sleeve. When the external threaded screw 4 is rotated, the Y-type bracket 6 does not rotate. The rotation of the external threaded screw 4 can change the extension length of the external threaded screw 4 inside the internal threaded sleeve 3, thereby driving the Y-type bracket 6 to move and adjusting the working height of the Y-type bracket 6 so that the height of the pipe bodies 25 on both sides is the same. When the threaded screw 22 is rotated on one side of the vertical plates 10 at both ends, the threaded screw 22 drives the blocking plate 2 to move under the action of the internal threaded sleeve 23. The positioning tail rod 24 slides with the vertical plates 10 at both ends, and the bottom of the blocking plate 2 moves left and right along the double bearing 12. The external threaded screw 4 moves along the long groove on the top plate 11 to realize the center line adjustment of the pipe body 25 and reduce the center offset of the two pipe bodies 25. The entire device can adjust the horizontal and center of the pipe openings of the two pipe bodies 25 to be welded respectively to ensure the pipe openings are aligned, thereby achieving the effect of rapid alignment. It can also assist the pipe bodies 25 in rolling welding, thereby improving the welding quality.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
